Couchbase Lite _replicate 400 BAD REQUEST with Cordova (PhoneGap) and Ionic Framework (AngularJS) $http on iOS

[n8s...@gmail.com]

I cannot get Coucbase Lite _replicate to work with Cordova (PhoneGap), using the Ionic Framework (AngularJS) and javascript $http call. $http always results in a 400 BAD REQUEST from Couchbase Lite. I'm uncertain about the proper config settings, nor how to debug the error at a deeper level (yet).

Due to my existing codebase, I want to use $http.post with Couchbase Lite. My Couchbase server and Sync Gateway are working together fine and are configured to use bucket shadowing between the sync bucket and primary server bucket.

DETAILS:

### CBL ERROR REASON: {"data":{"status":400,"error":"bad_request"},"status":400,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"url":"http://lite.couchbase./_replicate","data":{"target":”app-cbl","source":"10.69.0.117/firefly_sg/","continuous":"true"},"contentType":"application/json","headers":{"Accept":"application/json, text/plain, */*","Content-Type":"application/json;charset=utf-8"}},"statusText":"Bad Request”}

//

// Cordova code running on iOS

//

this.startReplication = function () {
    var deferred = $q.defer();

    // -- I have tried multiple configs, using both $http and $http.post, and also revised source / target --

    // -- This config is the closest to working, but results in a 400 error. --

    var config = {
        method: 'POST',
        url: "http://lite.couchbase./_replicate",
        data: {
            target: ’app-cbl’,
            source: ’10.60.0.100/sync_gateway/',
            continuous: 'true'
        },
        contentType: 'application/json'
    }

    $http(config).then(function (result) {
        console.log('### CBL SUCCESS RESULT: ' + JSON.stringify(result));
        deferred.resolve(result);
    }, function (reason) {
        console.log('### CBL ERROR REASON: ' + JSON.stringify(reason));
        deferred.reject(reason);
    }).catch(function (err) {
        console.log('### CBL CATCH ERROR: ' + JSON.stringify(err));
        deferred.reject(err);
    })
    return deferred.promise;
}

I have also tried different URLs for the sync gateway, but still get the same 400 error so I assume the error is originating locally on the iOS side.

Thank you for any assistance.

The value of “continuous” should be true, not “true”. I.e. a boolean not a string.

Oh, also, the “source” string is not a valid URL — it’s missing the protocol.

That was it -- fixed the 400 error -- Thank you!

I'm still not seeing a sync occur and not sure how to debug what's happening internally on Couchbase Lite from a Cordova / PhoneGap perspective.

Q1: Is there a way to get Couchbase Lite log / debug info from within a Cordova / Phonegap environment? Without it, I'm flying blind.

Q2: What is the correct way to include both Credentials and Channel information in the $http call? For example, should they be embedded in the url http://user:pass...@ipaddress.com or in the within the config object somehow? (Not Facebook Auth)

Hm, I’m not an expert on this, JChris is. Can you configure the command-line arguments passed to the app on launch? If so, you can enable logging that way. (I’m assuming you’re using the native/Cocoa CBL, not the Xamarin/.NET one.)

Yes, put the username/password in the URL. (They are stripped out of the URL before any HTTP requests are sent, so they won’t show up in proxy logs or anything like that.)
